About Costas Solar
We're a local team of solar specialists based in Costa Blanca North. We design, install, and maintain solar systems exclusively for villas — because villas need a different approach.

Built around the villa lifestyle of Costa Blanca North
Costa Blanca North attracts homeowners from across Europe — British, Dutch, German, Belgian, Scandinavian and Spanish families who have chosen the Mediterranean climate for its quality of life. The villas here are architecturally diverse: traditional fincas with terracotta roofs, modern minimalist builds with flat rooftops, hillside properties with complex orientations, and beachside homes exposed to salt air. Each requires a different solar approach. We have installed hundreds of systems across Moraira, Jávea, Benissa, Calpe, Dénia, Altea and Benidorm, and we understand the specific challenges of every area — from the strict urbanisation regulations in El Portet to the wind exposure on the Cumbre del Sol and the high-rise grid constraints along the Benidorm coast. This deep local knowledge means fewer surprises, faster permits, and installations that are engineered for your exact property.
Our team and certifications
Costas Solar is a registered installer with the Dirección General de Industria of the Valencian Community. Our engineering team holds the certifications required for self-consumption installations under Royal Decree 244/2019. We work exclusively with Tier-1 manufacturers and maintain direct relationships with Huawei, Longi, and BYD for equipment supply and technical support. Every project is supervised by a qualified electrical engineer who signs off on the installation before grid connection. We carry full civil liability insurance and provide written warranties on both equipment and workmanship. Our after-sales team monitors system performance remotely and responds within 24 hours to any service request — whether you are at your villa or managing your property from abroad.
Transparent pricing, no commission sales
We do not employ salespeople on commission. When you contact Costas Solar, you speak directly with an engineer who will assess your property honestly and recommend only what makes financial sense. If solar is not the right investment for your situation — for example, if your consumption is too low or your roof has significant shading — we will tell you. Our proposals include a full financial model: total investment, expected annual savings, payback period, IRR, and all applicable subsidies. There are no hidden costs, no pressure tactics, and no upselling of oversized systems or unnecessary batteries. We believe this approach builds trust and generates the referrals that sustain our business — over 60% of our new clients come from recommendations by existing customers.
